In 1996, I listened to Lofty Zadeh, the daddy of fuzzy logic, give his keynote speech at the ‘Artificial Intelligence in Design’ conference, Stanford University. He described the excitment of artificial intelligence in the 1950s and how Marvin Minsky, father of frames, told a press conference that 50 years on, computers would read and understand Shakespeare. When Zadeh asked Minsky what possessed him make such a claim, Minsky said that he didn’t know, he had just gotten carried away.
